' Application filed J'uly 'l, 1924. SeriallNo. 724,715.

To all whom it mag f 'co-ncernw 1 Be it known that I, J OHN .lVILLIAM J oNEs,a citizen of the United States,- residing at Clifford, in the county of illiamson and State of Illinois, have invented certain new and useful Improvements in Car- Uncoupling Devices, of which the following is a specification.

This invention relatesto car uncoupling devices and is designed primarily to pro vide new. and improved means, in a manner as hereinafter set forth, for disconnecting cars connected together by link connecting members.

The lnvention contemplates the provision of a drawbar having a hooked head projecting' beyond the end sill of the car, and this head has pivotally connected to one side thereof at a pointadjacent the bill of the hook, a swinging link adapted to be swung upwardly across that portion of the hook overhung by the'bill. A link connection is made between the freeswinging end of the pivoted link, with a crank having bearings in the body of the hook adjacent the point ofconnection with the drawbar, which crank extends outwardly to the side of the car where it terminates in a handle member. \Vhen a link connecting member of another car is engaged over the hook of the drawbar, and it is desired to uncouple the same therefrom, the said handle is raised swinging the crank to lift the swinging end of the pivoted link which raises the connecting link above the bill of the hook and allows the same to slip therefrom.

A further and final object of the invention is the provision, in a manner as'hereinafter set forth, of a car uncoupling device which is strong, durable, of easy operation, and inexpensive to manufacture.

The invention will be best understood from a consideration of the following detailed description taken in connection with V the accompanying drawings forming part of this specification, with the understanding that the invention is not confined to any strict conformity with the showing of the drawings but may be changed and modified so long as such changes and modifications mark no material departure from the salient features of the invention as expressed in the appended claim.

In the drawings:

Figure 1 is a perspective viewof the device embodying this invention showing a 6 at the end of the drawbar.

portionof a coupling link'engaged therewith.

. Figure 2 is 'a similar perspective view of thedevice shown disengaging the coupling link therefrom. I Referring 'now to the drawings in detail, wherein like numerals of reference indicate corresponding parts throughout theseveral views, a car flOOl lS indicated in dotted lines at-lhaving the projecting spaced bumpers-2.

The device embodying this invention. comprises an elongated fiat drawbar 3 adapted to be secured upon-or countersunk in the floor 1 and secured thereto by means of bolts or screws (not shown) which are passed through the apertures 4L therein. One end of the drawbar 3 has formed integral therewith a head, indicated as a whole by the numeral 5. This head, as. shown, 1s relatively narrow and pro ects above and below the bar 3 where it is secured thereto formingthe .upper shoulder This shoulder is rounded as is shown and has a bore transversely therethrough as at 7. The top portion of the head '5 is cutdownwardly and forwardly from the shoulder 6forming the downwardly inclined face Swhich cut in portion 8 is'extended well into the body of the head at the forward end thereof to form the overhanging or bill portion 9. This bill portion 9 and the upper part of the head integral therewitlnextends a substantial distance above the shoulder 6 as shown.

Pivotally secured by means of a pin 10,

to one side of the head 5 adjacent the upper edge and forwardly of the hill 9, is an arcuate link 11 the concave side 12 of which 'curvesabout the curved portion 13 of the hook, and the free end'of this link 11 has an the bore 7 in which it. bears, and this rod 19 has its ends extended beyond the side of the platform '1 where they are bent at; right angles to form the handles 20.

The link 11 is normally in the position shown in Figure 1 andwhen in this position the link 21 which forms a coupling element carried by another car, is engaged over the bill 9 of the hook and extends across the concave edge 12 of the link. When it is Ill;

desired to disconnect the link 21 from the hook the handles 20 are swung upwardly,

consequently raising the crank arm 18 which arcuate link 11 is raised, it willraise the;

link 21 from the curved face 13 of the hook until the swinging end of :the link 111 israised to the position above the bill 9, as indicated *ingEigure 2, whereupon the concave surface 12 at the pivoted end ofg-the *link avill1be substantially :fiusl with' the "top of the bill and the "link 21 will slip thereover to disconnect the cars. I

From the foregoing description it may be seen that a very simple iand {eflicient uncoupling device is provided ibyhiea'ns of which cars can be "uncoupled Without the necessity of a brakeman getting "between them.

Having thus described my invention what I-cle'im is: v

.A-n uncoupling device of the character set (forth comprising-a drawbar, a head upon one end thereof formed toprovide an upmember, a fiat arcuate link having one end pivotally secured to the bill of said hook, and lying against and having the swinging end directed downwardly :a-nd iIlWBIPdlyffOl lowi ng the-curvature of the 'inner qaortion of said Ebilh and means engaging with the :t'ree inner end of said Elink to li t t the said inner end across the gu'l let of the =hook"to a point above the bi ll to raise the'-cou1; ling 'me'mberito :ajpos'ition where it will slip freely over the head.
